Recommended reading: Wearing sunglasses indiscriminately can hurt your eyes. Have you ever heard of 'sunglasses syndrome'? It does exist, and it often appears in some fashionable young people. After wearing sunglasses for 1 to 2 weeks, symptoms such as skin numbness and unconsciousness will appear in the eye sockets or between the cheeks, and the nose will feel uncomfortable when breathing. It is like a cold, and some people may also feel that there are small bugs. Crawling on the face, sore eyes, etc. This is because they often wear glasses with wide sides, thick frames, and heavy weights. In addition, some people like to wear sunglasses, regardless of time and occasion, outdoors or indoors, even at dusk, watching movies, watching TV, which will increase the burden on the eyes, cause eye muscle tension and blurred vision. In severe cases, symptoms such as dizziness, dizziness, and inability to see for a long time may occur. These symptoms are caused by the abuse of sunglasses. To choose a good pair of glasses, in addition to paying attention to the style of brand sunglasses, the following three details cannot be ignored. There is an anti-ultraviolet logo and anti-ultraviolet is the primary function of sunglasses. Some sunglasses have '100% anti-ultravioletIf you wear low-quality sunglasses that cannot block UV rays, more UV rays enter your eyes than when you don’t wear sunglasses, which will more easily cause eye damage. After a long period of time, it can cause cataracts, such as eye pain, corneal edema, and corneal epithelial shedding. . Regular spectacle shops generally have instruments to test the ability of sunglasses to prevent ultraviolet rays, which can detect whether your choice is correct. The quality of spectacle lenses from street stalls and hawkers is often not up to standard, so it is best not to buy them. Choose gray, brown and green lenses The color of the lens should be based on the principle that the color of the surrounding environment is not distorted, the edge of the object is clear, and the signal lights of different colors can be effectively identified. The colors of the lenses are gray, brown, and green because the lenses of these colors absorb infrared and ultraviolet rays better. Medium-depth lenses generally speaking, the darker the lens, the stronger the shading effect, but it does not mean that the ability to prevent ultraviolet rays is stronger. The anti-ultraviolet function of sunglasses is also related to the lens material and craftsmanship. The lenses are generally medium-depth. Of course, if a strong shading effect is required, darker lenses should be selected. But cyclists or motorists should not choose too dark lenses, otherwise it will be difficult to recognize the color of traffic lights. Different groups of people will choose sunglasses according to different preferences and different uses, but the most fundamental thing is to start from the basic principle that can protect the wearer's eyes from damage. Reducing strong light irritation, clear vision without distortion, UV protection, color recognition without distortion, and accurate identification of traffic signals should be the basic functions of sunglasses. As non-professionals, it is difficult for us to judge by ourselves whether the quality standards of brand sunglasses are met. Therefore, everyone is encouraged to go to a regular eyeglass shop to choose a regular manufacturer to produce, and clearly mark the sunglasses that have the function of blocking ultraviolet rays.
